222 * use_dma=1 - Enable DMA
224 Rx DMA only)
225 * dmasize=# (16 or 64) - DMA size 16K or 64K. Default value is set to 16.

298 i) Cirrus recommend that the cs89x0 use the ISA DMA channels 5, 6 or
299 7. You will probably find that other DMA channels will not work.
301 j) The cs89x0 supports DMA for receiving only. DMA mode is
303 with large ping packets consumes 82% of its CPU capacity in non-DMA
304 mode. With DMA this is reduced to 45%.
312 l) If during DMA operation you find erratic behavior or network data
320 n) If the cs89x0 driver is compiled directly into the kernel, DMA
322 'cs89x0_dma=N' where 'N' is the desired DMA channel number (5, 6 or 7).
336 The DMA Rx buffer size is hardwired to 16 kbytes in this mode.
360 4.3 COMPILING THE DRIVER TO SUPPORT Rx DMA
362 The compile-time optionality for DMA was removed in the 2.3 kernel
363 series. DMA support is now unconditionally part of the driver. It is
